Abstract (en)
[origin: WO2015188966A1] The invention describes a drive circuit (10) for generating a sawtooth voltage (Vpp) for a voltage controller, having at least one resistor (16) and at least one capacitor (20) for generating the sawtooth voltage (Vpp) based on an input voltage (Vin), wherein the resistor (16) or the capacitor (20) has a plurality of elements (21, 22, 24, 25) which can be individually switched, wherein a counter (33) drives at least one element (22, 24, 25) for generating sawtooth voltages of different amplitude, and wherein a comparator (37) is designed to stop the counter (33) when the sawtooth voltage (Vpp) reaches a prespecified voltage (Vref).
